Over 70 million people in North America struggle with sleep. Circadian disruption is linked to metabolic disease and even cancer risk. Yet most people still don't understand what's actually controlling their energy. In this episode of Uncover Your Eyes, Dr. Meenal Agarwal breaks down the science of our circadian rhythm and how light, screens, and modern environments are reshaping your sleep, hormones, and daily energy. You'll learn how your brain's master clock, the suprachiasmatic nucleus (SCN), responds to light, why indoor living is disrupting your biology, and how simple changes can reset your system naturally. This episode connects vision science, neuroscience, and preventive health to help you understand why so many people feel tired, wired, and out of sync—and what to do about it. In this episode, you'll uncover: 🎧 How your body's master clock, the SCN, actually works 🎧 The difference between indoor vs. outdoor light exposure 🎧 How screens disrupt sleep, especially in children and teens 🎧 Why puberty is a critical window for circadian development 🎧 The health risks of chronic circadian disruption 🎧 How much morning light you actually need to reset your clock If you are a parent, healthcare provider, educator, or high-performing professional, this episode will change how you think about circadian rhythm, sleep, energy, and mental health.
